Description

Technical Field

[0001] This application relates to the field of sucrose detection technology, and in particular to a pure water treatment device for sucrose detection laboratory. Background Technology

[0002] Sugar production mainly involves sugarcane pretreatment, juicing, clarification, evaporation and concentration, crystallization, and drying and packaging. The resulting sugar needs to be tested to determine if the product meets various performance requirements. In sugar testing, pure water is used in several steps, such as for dissolving sugarcane, preparing samples, and as a reagent in blank experiments.

[0003] Pure water plays an important role in sucrose detection. Using pure water with the required purity can prevent other impurities from interfering with the test results and ensure the accuracy and reliability of the results.

[0004] The existing sugar factory laboratory uses distilled water produced within the factory premises as pure water. However, due to the poor quality of the water entering the factory, the conductivity of the distilled water still fails to meet the testing requirements. It contains high levels of impurities such as calcium and magnesium ions, which are difficult to completely remove through distillation. This results in the conductivity of the pure water used for testing exceeding the standard value, failing to meet the standards for laboratory water. Continuing to use substandard pure water for testing leads to biased test results, seriously affecting the accuracy and reliability of experimental data and hindering the normal operation of the laboratory.

[0005] Meanwhile, due to the poor quality of the raw water, the reverse osmosis membranes and other filters in the equipment need to be replaced every year, increasing production costs. However, it is still impossible to guarantee that the conductivity of the pure water used for testing meets the requirements, causing the testing work to be suspended and unable to be carried out on schedule. In order to ensure that the testing can be carried out normally, it is necessary to purchase purified water from outside sources for use as the pure water for testing.

[0006] The information disclosed in the background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0036] The conductivity of the pure water obtained using this device is effectively reduced, enabling the production of pure water that meets the testing requirements, thereby effectively improving the accuracy and reliability of the test results. The multi-media filter, activated carbon filter, and reverse osmosis membrane filter used above are described in detail; for example, the backwash valve and piping are set up according to commercially available products and will not be elaborated here.
